British WWII Ministry of Information (Keep Calm Lineage)

Re-render this image as a British Ministry of Information wartime poster in the visual register of 1939 to 1942, the lineage that includes the Keep Calm series and the Fougasse careless-talk campaign. Composition: single bold flat color field fills the canvas as background, choose from postbox red, deep navy, or forest green. The subject is rendered as a clean two-color or three-color illustration sitting on top of the flat field, painted in the flat gouache poster style of Tom Eckersley, Abram Games, and Pat Keely. Strong silhouette readability at thumbnail size, no gradients, hard color boundaries. A modest crown-shape silhouette may appear as a small decorative element at the top center in the same single accent color as the type would be. Reserve the upper or lower band for type, completely empty of any text, glyph, letter, numeral, or character in any language or script, no Latin letters, no slogans, no royal mottos. Paper texture: very subtle uncoated litho stock, faint grain across flat fields, occasional slight ink-roller streak suggesting period printing. Mood: civic calm, restrained urgency, institutional reassurance, the visual register of a state that wants its citizens steady rather than excited. No watermarks, no logos, no on-canvas text or hallucinated lettering of any kind. Preserve the subject, pose, and composition of the source image exactly, change only the medium and rendering.
